IEC 62153-4-9:2018 is also available as

IEC 62153-4-9:2018 RLV

which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.



IEC 62153-4-9:2018 applies to metallic communication cables. It specifies a test method for determining the coupling attenuation a

C

of screened balanced cables. Due to the concentric outer tube, measurements are independent of irregularities on the circumference and external electromagnetic fields. A wide dynamic and frequency range can be applied to test even super screened cables with normal instrumentation from low frequencies up to the limit of defined transversal waves in the outer circuit at approximately 4 GHz. However, when using a balun, the upper frequency is limited by the properties of the balun. Measurements can be performed with standard tube procedure (respectively with standard test head) according to IEC 62153-4-4 or with open tube (open test head) procedure.


The procedure described herein to measure the coupling attenuation a

C

is based on the procedure to measure the screening attenuation a

S

according to IEC 62153-4-4. This second edition cancels and replaces the first edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:


– two test procedures, open head and standard head procedure;


– measuring with balun or with multiport respectively mixed mode VNA;


– extension of frequency range up to and above 2 GHz.
